I '0 all whom it may concern Be it known that I. lrumr @Lrvnno, me-

chanical engineer, a subject of the King of l'taly, residing at cnoaltaly, have invented a useful Improvement in Car-(Iouplings, of whichthe Following is a specification. This invention relates tothemechanisms for the ai'itomatic coupling of cars,essentially formed oftwo jaws each of them rotating around a journal. and ot' a link adaptedto remain engaged between said jaws by re: son ot the impact or pressureof the latter against the former. well as for the interposition. at theright moment, of a convenient locking member. a I

fLCCOlfdlllg to present invention the above stated rotating jaws are soconstructed to remain open on the part designed; to receiv the shock ofthe lin: and shut on the. part where the interposition of the lockingmemher is taking place.

By drawing two cars one near to the other, the link carried by one ofthem actuates the jaws of the other car so as to be drawn together andclosed'on the part of the said link, while they will open themselves onthe opposite part and in this position will get locked by reason of theinterposition, in the latter, of a locking member.

The link is entirely embraced by the jaws, just like a pin connectingrod in its bearing, whereby the coupling is effected.

The locking member is independent from the jaws and exercisesitst'unction at the right moment. under the influence, for example of aweight lever, when, under the action of the link, said jaws will openthem selves on its side, under the action, too, of said weight leverplaced in a convenient position.

The accoi'i'lpanying drawings illustrate, by way of example, oneconstruction of the invention.

In these drawings: Figure 1 shows a longitudinal vertical section of thecoupling mechanism in locked position; Fig. 2, is a similar view showingthe device in the position while the coupling is taking place; Fig. 3shows a side elevation partly in section 01" the link which forms one ofthe parts of the coupling device; Fig. 4 shows a plan view of thearrangement of the pair of coupling mechanisms at the end of the cars;

jaw -l and and 2 is thelink which remains en aged between them. On thedrawbar l are firmly secured the two spaced walls 3 between whichsaid-jaws are located, said jaws being pivoted upon the journals Thejunction of the two walls over the bar 1 realized by means ol b olts 7and they are kept at the required distance one from the other by bandrings 7 placed around said bolts. On. the side of the link the walls 3are connected, by means of a part. of the bolts '7 themselves, to a cup8 possessing ears 9. This cup has the object of guiding the link to thecenter of the jaws l and 5. This opportunity is OllfiIECl in the case ofthe coexistence of the usual hand coupling mechanisn as well as with thecoupling object of the present invention.

By drawing two cars one near torthe other the link 2 guided by the cup 8will strike or press against the center of the twoj'aws, thereby causingtheiropening on the side of the locking member 10. This latter guided bythe walls 3 is controlled by the angle levers 1l-l2l3, and this one, inturn, by the forked connecting rod ll operated by the lever 15, runningloose on the shaft 18 controlled by the notched sleeve 24 keyed on theshaft 38, and this latter controlled by the lever 20 under the action ofa weight or spring 27 guided along the rod 21 or by means'of anotherconvenient arrangement.

When the lever 19 driven by the spring '27 is in the position asrepresented in Fig. the locking member 10 will press against the jaws,and as soon as these, by reason of the impulsion or shock of the link,have opened themselves to a certain extent, the aforesaid locking memberwill then insert itself between them causing them to get locked in theposition as shown in Fig. 1, whereby the coupling is eiiected.

When it is required to uncouple the cars it is only necessary to bringthe lever 19, by means of lever 20, in the position as shown in Fig. 2,thus enabling the sleeve 24, 2% which rotates with the lever itself, topress with its notch against the notch shows a plan viewof the mechanisma of lever 15, thereby exercising an action 1 uponithe angle lever11i12131by means warranty of working since the weightof the variousparts 'contrlbutesto keep the niechanism shut.

Having 'now particularly described and as-V certalned the nature of mysald lnvention' and inwhat manner the same is to be performed,I declarethat what I claim is:

1. A car coupling ofthe character de-i scribed comprising in combinationjaws pivoted intermediate their ends for movement.

in avertical plane, the pivoted aXis of the upper. jaw; being situatedforward of the center of 'gravity'th'ereof, and the pivotal axis of thelower jaw being located to the rear of the center of gravity thereof.

2. In a car coupling of the character described, the combination of twojaws, bearings upon which the jawspivot, the pivoted axisaof the upperjaw being situated forward of the center of gravity thereof and thepivoted aXis of the lower jaw being 10- Gated to the rear of the centerof gravity thereof, a link carried by one of the cars adapted to actuatethe jaws of the car for closing the same, and a locking member forlocking said jaws over said link, the jaws of the other car beingadapted to remain open under the action of the gravity. f

3.1L car coupling comprising a pair of pivoted jaws, a link or the likeadapted to be engaged by the jaws, said jaws being opv 'erated by thecontact of the link so as to engage the link, and means for locking thejaws in the closed position, said jaws tending to remain in an openposition under the action of'their own weight.

In testimony whereof I afliX my signature in presence of two witnesses.
